Yaseen Construction Products supplies Extruded Polystyrene (XPS) insulation boards for commercial buildings, industrial facilities, infrastructure and residential developments. XPS is a rigid, closed-cell thermal insulation material used in roofs, walls, floors and below-grade construction.
We source XPS boards according to project requirements for thickness, thermal conductivity, compressive strength, water absorption, edge profile and board dimensions
Extruded Polystyrene (XPS) is a rigid thermoplastic foam insulation manufactured through an extrusion process that produces a predominantly closed-cell structure. Its combination of low thermal conductivity, moisture resistance and compressive strength makes it suitable for building-envelope insulation and selected load-bearing applications.
XPS boards help reduce heat transfer through roofs, walls, floors and foundations. In warm climates, properly designed insulation systems can reduce unwanted heat gain and improve building energy performance.
Yaseen Construction Products sources XPS insulation boards for commercial developments, residential buildings, industrial facilities, cold-storage projects and infrastructure construction. We support specification-based procurement, including requirements for board thickness, thermal resistance, compressive strength, edge configuration and applicable building standards.
Rigid boards designed for general thermal insulation applications in compatible building systems. These are commonly specified for roofs, floors and walls where the required thermal and mechanical performance can be achieved.
Engineered for applications where insulation must resist sustained or temporary compressive loads.
Typical uses include ground-bearing floors, foundation insulation and selected heavily loaded roof assemblies. Long-term compressive creep performance must be considered in addition to short-term compressive strength.
In protected membrane or inverted roof systems, XPS boards are installed above the waterproofing membrane.
The insulation must be suitable for the expected moisture exposure, roof loading and drainage arrangement. System design should account for water flow, thermal performance and protective ballast or paving.
Selected XPS grades can be incorporated into cavity walls, external insulation systems and other approved wall assemblies.
Compatibility with adhesives, render systems, fire-safety requirements and facade specifications must be verified before installation.

The existing Yaseen listing specifies a 600 × 1000 mm sheet and density of 32–35 kg/m³. Other properties must be verified against the selected manufacturer’s technical data sheet.
The effectiveness of XPS insulation is determined primarily by its declared thermal conductivity and installed thickness.
Thermal resistance is calculated as:
R = Thickness (m) ÷ Thermal Conductivity (W/m·K)
For example, an XPS board with a thickness of 50 mm and an assumed thermal conductivity of 0.034 W/(m·K) has a calculated material thermal resistance of approximately 1.47 m²·K/W.
This is an illustrative calculation, not a declared performance value for a specific Yaseen-supplied board. Actual design values should follow the selected manufacturer’s documentation and applicable building regulations.

Before specifying XPS insulation, engineers and procurement teams should evaluate:
Thermal performance: Required insulation thickness, declared conductivity and target U-value.
Compressive loading: Short-term strength and long-term compressive creep under expected loads.
Moisture exposure: Water absorption characteristics and the drainage arrangement.
Fire safety: Required reaction-to-fire classification and compatibility with the complete building assembly.
Installation environment: Temperature, substrate condition, adhesive compatibility and mechanical protection.
Board geometry: Dimensions, thickness tolerances and edge configuration.
Project compliance: Approved technical data sheets, test reports and applicable building regulations.
XPS insulation is generally supplied as rigid boards, packed in manufacturer-standard bundles or protective wrapping.
The existing product listing specifies:
Board size: 600 × 1000 mm.
Nominal board area: 0.60 m².
Listed density: 32–35 kg/m³.
Supply unit: Sheet.
Other board thicknesses, dimensions, densities and packaging quantities may be sourced according to manufacturer availability and project requirements.
Buyers should confirm the thickness and number of boards per pack before comparing prices.
Yaseen Construction Products can review XPS insulation sourcing requirements against recognised product references, including:
DuPont STYROFOAM and ROOFMATE product ranges.
E-Foam.
E-Roof, E-Wall and E-Floor insulation references.
Other approved XPS insulation manufacturers.
Equivalent products should be evaluated against thermal conductivity, compressive strength, water absorption, board dimensions, fire classification and relevant standards.
Brand references are provided for product identification and comparison. They do not imply manufacturer affiliation, stock availability or automatic technical equivalence.
XPS insulation prices depend on thickness, density, compressive-strength grade, thermal performance, board dimensions, manufacturer and order quantity.
For accurate quotations, buyers should provide:
Required XPS board thickness.
Density or specified compressive-strength grade.
Thermal conductivity or thermal resistance requirement.
Board dimensions and total coverage area.
Application, such as roof, wall, floor or foundation.
Approved brand or technical specification.
Delivery destination and required quantity.
For project procurement, comparing price per square metre at the same thickness and performance grade is generally more useful than comparing sheet prices alone.

Extruded Polystyrene is a rigid, closed-cell foam insulation manufactured from polystyrene resin. It is used to reduce heat transfer through roofs, walls, floors and foundations. XPS boards are selected according to thermal conductivity, thickness, compressive strength, moisture exposure and building-system requirements.
XPS is produced through extrusion, while Expanded Polystyrene (EPS) is manufactured by expanding and moulding polystyrene beads. XPS generally offers relatively low water absorption and is available in high-compressive-strength grades. However, actual thermal and mechanical performance must be compared using specific product data rather than material names alone.
The required thickness depends on the target roof U-value, declared thermal conductivity, climate, roof assembly and applicable energy regulations. An insulation designer should calculate the required thickness using the complete roof construction rather than selecting a standard thickness without assessment.
Yes. Suitable XPS insulation boards are commonly used in inverted roof systems, where the insulation is installed above the waterproofing membrane. The system must address water drainage, ballast, wind uplift, moisture exposure and thermal performance.
Density measures the mass of the foam per unit volume, normally expressed in kg/m³. Compressive strength measures resistance to compressive loading, normally expressed in kPa. Although density can influence strength, it should not be used as a substitute for verified compressive-strength data.
XPS has a predominantly closed-cell structure and generally exhibits low water absorption. However, XPS boards are not a replacement for a properly designed waterproofing membrane. Joints, penetrations and the complete construction assembly must be addressed separately.
XPS is a combustible polymer insulation material. Fire performance depends on the product formulation, protective layers and complete building assembly. The relevant fire classification and local building-code requirements must be verified before specifying XPS.
The current Yaseen product listing specifies a 600 × 1000 mm board with a listed density of 32–35 kg/m³. Thickness, edge profile and alternative dimensions should be confirmed for the selected grade before ordering.
Divide the total insulation area by the coverage of one board, then account for cutting losses and installation details. A 600 × 1000 mm board covers 0.60 m², so 100 m² requires approximately 167 boards before allowing for wastage.
XPS can be installed in compatible protected-membrane roof systems, but material compatibility and installation methods must follow the approved system design. Adhesives, solvents, drainage layers and protective materials should be checked for compatibility with both the insulation and waterproofing membrane.
The main pricing factors include board thickness, density, compressive-strength grade, thermal conductivity, dimensions, manufacturer, order quantity and delivery destination. Buyers should compare equivalent technical grades and cost per square metre.
